Letters Patent No. 73,990, dated February 4, 1868.

IMPROVEMENT IN STOVE-DRUMS.

TO ALL WHOM IT MAY concerns;

Be it known that I, M. S. MORGAN, of Olintonville, in the county of Kane, and State of Illinois, have invented a new and useful Improvement in Stove-Drums; and I do hereby declare that the following is a full and exact description of the construction and operation of the same, reference being had to the accompanying drawings, and-to the letters of reference marked thereon, making a part of this specification, in which- Figure 1 is a perspective-view.

Figure 2 is a vertical transverse'section of the some.

Figure 3 is a transverse section on line e e.

Figure 4 is a transverse section on line a: a:-

Similar letters of reference, where they occur in the separate figures, denote like parts in each of the drawings.

My invention consists, first, in so constructing the drum as to form an air-chamber between the outer casing and the pipe, around which the fire from the stove may pass, in combination with a system of vertical flires passing through the lower and upper end-of the outer casing into said chamber, whereby a great amount of heat may be obtained by means of the cool air passing into said chamber through the lower system of fines, and being heated and thrown off into the room through the upper system of fines thus the greatest possible amount of heat can be obtained; second, constructing the outer casing so as to be capable of a rotating'movemcnt, in combination with two or more vertical springs or scrapers, attached, one to the inner side of the outer casing, the other to the outer side of the casing of the airchamber, and extending theentire length of the latter, whereby, as the outer casing is given a rotating movement, the springs or scrapers coming in contact with or against the opposite sides or casings, the accumulated soot is removed therefrom and is caught in the soot-box below, thus leaving the surface of the drum clean, thus admitting of greater amount of heatpassing through the same.

' To enable others skilled in the art to make and use my invention, I will proceed to describe the same with reference to the drawings.

i A represents the outer casing of the drum, which may be of any thin metallic substance, saidcasing being supported at the lower end by means of flanges protruding outward from and around the outer sides of the soot-boxL, which is coupled to pipe B of the stove. Within said casing is a seconddrum or air-chamber, 0, its size being such transversely as to leave a vacant space between its' sides and the s ides of the outer casing, of from one-half to three-fourths of an inch, said chamber having also a cavity through its centre vertically, oi' the size of the cavity in pipe B, which may be closed at any given time by means of damper '1. The objectsof leaving the cavity through and around, said chamber is to give .a greater heating-surface; Attached to the 1 inner side of case A is a vertical spring or scraper, H, which extends across the cavity and against the sides of chamber C, said chamber. having also attached to its side a, like spring or scraper, H", that extends across and against the side of case A, whereby, when said outer case is rotated once around, the edges of said scrapers come in contact with or against the opposite'sides, thus removing the soot which may collect within said cavity. The same is caught in the soot-box L. Said air-chamber is provided with two systems of air-dues, the lower system of flues,f, extending downward from said chamber 0 through thelcwer end of the outer casing or soot-box L, the upper system e passing upward from said chamber through the upper end of said casing, as shown by fig. 2. The object of this style. of air-chnmben with its relative combination of fines, is to allow a, current of cool air to pass into said chamber through the lower system of fines, Whichis heated and thrown 05' into the room by means of the upper system, whereby all the heat is saved, and a room can be heated and keptto a more even temperature with a less amount of; fuel than with any of the heretofore-known similar arrangements.

Having thus described the nature and object of my invention, what I claim asnew, and desire to secure by Letters Patent, is- Y Rotating case A, in combination'with soot-box L, scrapers Hand H", substantially as and for the purpose described.-
